摘要

Improvements in gear change mechanisms in planetary frames, consisting essentially of the arrangement of a vertical axis that by its upper or lower ends is related through bearings respectively to a coupling plate that receives motor movement and the bedframe whose axis is surrounded by a sleeve that at its lower end has a pinion attached, while at the bottom it is carrying one of two friction discs, a pinion being mounted freely rotatable on said sleeve, at the central part of which the other is fastened friction disc, whose two discs fit inside a drum provided with longitudinal grooves in which fits a guide to which a ring possessing a throat has been attached with which a single control device is combined to determine the displacement, on a tube that surrounds the shirt, with a clutch integral with said ring and capable of being applied to one or the other of the friction discs to cause the change of speeds.
